An AI voice agent is the voice-mode version of an autonomous agent. It accepts a spoken request, decides which tools to call (CRM lookup, calendar check, refund, dispatch), and produces a spoken response, all in under two seconds of latency on a good day.
The hardest engineering problems are not in the conversation itself. They are in voice authentication, in deciding when to hand off, in keeping latency low while the model thinks, and in writing the result back to a system of record in a form that an auditor can read.
A useful voice agent does not feel like a chatbot reading prompts. It pauses, acknowledges, asks clarifying questions, and resolves the call. The benchmark is whether the customer would have noticed they were not talking to a person, and whether a human would have done the same work, the same way.
Vorel ships voice agents that pass a defined latency SLA (p50 under 1.2 s) and write every action into the CRM your team already reads.
